摘要
应用有限元法对某地铁车站隧道开挖引起的地表沉降和水平变形及隧道围岩的应力分布进行了模拟分析.结果表明,在隧道开挖过程中,采用边开挖边支护的方法可以有效减轻地表沉降及水平变形.
By the finite element method, this paper makes simulation analyses on the surface subsidence and horizontal deformation and the tunnel surrounding rock stress distribution afterthe tunnel excavation in a metro station. The results show that it effectively reduces surface subsidences and horizontal deformations to adopt the method of digging while supporting in theprocess of tunnel excavation.
